BENGALI VOWEL SIGN O maps to BENGALI VOWEL SIGN E and shifts position

When copy/pasting or importing/placing Bengali text from Google Docs, Bengali vowel O (U+09CB)ো maps to vowel E (U+09C7)ে and shifts position in the word.

The font in Google Docs is Arial unicode. I'm using Adobe Bengali in InDesign 2018.

World-ready composer is applied, Bengali language dictionary selected and autocorrect disabled.

Correct examples :
প্রকাশযােগ্য

যােগেশচন্দ্র

Becomes:

When I paste the incorrect word from InDesign into this form it appears correctly so I had to take a screenshot and save as a jpeg from Pshop.
Unfortunately this is blocking a significant amount of publishing work planned for InDesign.
